Old Genset, replaced in September of 1999
Note, Please go to this area for a write up of our new VW-powered 10KW genset.
These pictures are of my standby generator setup. The engine is a
Continental Y-69 from an International Harvestor combine of early '40's
vintage. The bellhousing is from a different engine, having provisions
for an electric starter. There's a home-made plate to adapt a Corvair
starter to the bellhousing; the Corvair ring gear is shrunk onto the
The generator is an old Miller welder/alternator. It runs at 1800 RPM to
provide up to 5 KW of 60-cycle AC power, or at 3000 RPM to provide
100-cycle AC welding current. Later models have a rectifier to provide
DC welding current. There's also an outlet on the end of the unit to
provide 115 VDC at welding speeds to run a trouble light, grinder, or
whatever without changing the switch back and forth.
This first picture is an overall shot taken through the door of the
metal shed. It was taken at an earlier time than the following shots.
As the engine uses a gallon of fuel per hour, we added this 9-gallon
tank in addition to the standard 6-gallon capacity so we can get some
sleep during a power outage. It's plumbed in like this, so we can run
either or both tanks; we mounted the auxilary tank with the filler neck
at the same elevation as the original.
Here's an overall view of the 03 RH side of the engine showing the spark
arrestor on the exhaust stack and the coil, resistor, and relay for the
addon electronic ignition. Those old I-H magnetos aren't worth beans,
but are easy to bypass.
From the LH Side, you can see the Motorola 30-amp alternator, regulator,
and addon drive sheave for the alternator.
This shows the Corvair starter and adaptor plate. I also installed an
oil filter base that uses a VW filter; it has a restriction to control
the flow of oil so as to not starve the engine. This is a bypass filter
setup; the engine had no filter originally.
A closeup of the LH side shows the adaptor plate that connects the
alternator frame to the bellhousing. There's a shaft/adaptor plate
inside that drives the alternator rotor; it's just visible through the
crack in the exact center of the picture. The rotor has only one
bearing, the drive end is carried by the engine crankshaft.
The new genset is shown here.
